Mike, how about a first round mock plus one? I'm curious: what do you have the Pats doing at #33?
A couple of thoughts: if the draft unfolds that way then the Pats would have some interesting choices at #17: Watt? Jordan? Maybe try to trade down a few spots with the idea they can get a similar value later, and add an extra pick in the process? Fans will have plenty to debate regardless of what happens.
While I do believe the Patriots will trade a pick in exchange for another 2012 draft pick, to me it does not make sense to do so with the 28th pick unless they're getting something else like another 2nd or 3rd this year also. The general rule of thumb is that if you trade into the following year you move up one round. This trade is only a first for a first as it appears right now, so unless there is something else involved it makes very little sense to me. I would look for the Pats to trade their own 2nd at #60 for a 2012 1st, or 3.92 for a 2012 2nd instead.
Edit: just saw your comment above regarding the trade, that makes more sense now.
